Test Automation Engineer (QA) - Cloud Networking - Project based

Job Description

Our Quality Assurance team ensures that MidoNet ships free of bugs, performance/scaling regressions and with all components working seamlessly together (CLI, GUI, distributed network controller). Our QA engineers are experts at using MidoNet and deeply familiar with OpenStack and CloudStack. The QA engineers do manual and automated testing of MidoNet and its cloud software integrations. The QA engineers help with root-cause analysis and help drive improved testing and coverage in the entire code-base. The QA team also maintains and evolves a sophisticated cloud-based framework that allows launching and testing a MidoNet cloud within a public cloud (like AWS or Rackspace) - this enables agile and flexible testing at small and large scales, especially scales we would not be able to test with Midokura-owned hardware.

We seek individuals that are passionate about networking and cloud, that have built or tested parts of a network infrastructure or cloud. The successful candidate will work with an exciting array of technologies in networking, cloud-computing and virtualization and will be part of a team that is innovating how virtual networks are built and operated.
